This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.

1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.

2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.

3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.

4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

A psychological sci-fi thriller aboard an orbital quarantine station. Interrogate 10 astronauts, identify 4 infected crew members, and prevent a mutiny before Earth reentry.

RED PROTOCOL is a psychological sci-fi thriller about the final shift aboard an orbital quarantine station.

Before returning to Earth, every astronaut must pass one last interview. Today, a long-range expedition of ten exhausted crew members arrives at your station. Your job is to question each of them, identify carriers of an unknown psychological infection, and decide who is cleared for descent and who must be isolated.

The problem is that this disease does not make people violent or insane. It makes them too perfect. Too calm. Too complete. Some infected crew members have nearly lost their inner contradictions. Others are only beginning to change and can still hide behind convincing, human explanations. Every one of them wants to go home. Every one of them is ready to tell you exactly what you want to hear.

Your mission is to find 4 infected people among 10 crew members.

But every mistake raises the stakes:

- let the infected pass, and the contamination reaches Earth;

- isolate too many people, and the station edges toward mutiny;

- once 6 crew members are flagged, the quarantine system enters a critical state.

Each interview is built around questions, answers, and doubt. You can keep pressing when something feels wrong, or end an interrogation after a single answer if you are already convinced. The deeper you go, the more detail you uncover — and the easier it becomes to make the wrong call.

In RED PROTOCOL you will face:

- 10 crew members with distinct biographies, fears, and personal reasons to return home;

- hidden infected assignments that change between runs;

- morally tense decisions with no comfortable answers;

- multiple endings shaped by your suspicions, mistakes, and the station's rising tension;

- a cold orbital atmosphere where the threat is not a monster, but flawless behavior.

This is not a story about something lurking in the dark. It is a story about a person who sounds just a little too perfect to be real.
